GUN PROPELLANT DEVELOPMENT ACTIVITIES IN THE NETHERLANDS

摘要

In the Netherlands, the experience on continuous twin screw extrusion processing of composite and conventional propellants, as well as on internal ballistics in general has been enlarged over the past years. Propellant optimisation for both performance in a gun and processibility is aided by combining models that relate both. Recent efforts include the development of LOVA propellants, new propellant charges for large calibre K.E. and E.R. munitions, and temperature independent propellant. Go-extrusion is currently being investigated in order to improve properties like ignition, performance and erosivity of conventional and LOVA propellants. Design of and optimisation of production processes for new propellant compounds are investigated.
